YC-backed Dalus wants a senior React engineer in Germany to build the interface for software that helps teams design rockets, satellites, EVs, aircraft, and other complex hardware systems.

Dalus, a Y Combinator W25 company founded in 2024, is hiring a senior software/frontend engineer for its Germany office as it builds AI-powered design software for complex hardware systems.
The role pays €70,000 to €90,000, with 0.20% to 1.00% equity. Dalus lists Munich and remote work in Germany as options, with broader DACH availability preferred. The company also lists San Francisco, Los Angeles, and Melbourne among its locations.
Dalus targets systems engineers who design rockets, satellites, defense systems, electric vehicles, aircraft, and nuclear plants. The company says those teams still rely on older desktop tools that slow down engineering work and make complex design data harder to manage.
The job centers on React and product interface ownership. Dalus wants an engineer with five to eight years of experience, strong UI judgment, polished product work, and comfort owning frontend decisions on a small team. German helps, but the company lists it as a plus.
The company’s pitch fits a pattern across industrial AI startups: bring software ergonomics from modern developer tools into fields that still depend on legacy engineering systems. The hard part sits in the interface. A systems engineer may need to inspect requirements, dependencies, simulations, constraints, and design trade-offs in one workflow. Dalus needs a frontend that can make dense engineering data usable without hiding the detail experts need.
Dalus has a three-person team and active YC status. The posting names Sebastian Völkl and Eliot Khachi as founders. YC backing gives Dalus access to early startup capital and network support, though the posting does not list a separate funding round or amount.
The interview process includes calls with the CEO, CPO, and CTO, followed by a hands-on code challenge. That sequence suggests the hire will work across product, engineering, and founder-level decisions rather than join a large frontend group with fixed responsibilities.
For senior frontend engineers in Germany, the role offers a clear trade-off: lower cash compensation than later-stage enterprise software roles, paired with meaningful equity and high product ownership. The market question for Dalus remains whether hardware teams will move core design workflows from entrenched tools into a new AI-native platform.
